Air at atmospheric pressure and a temperature of 25°C is in parallel flow at a velocity of 5 m/s over a 1 -m-long flat plate that is heated with a uniform heat flux of 1250 W/m2 . Assume the flow is fully turbulent over the length of the plate.

(a) Calculate the plate surface temperature, Ts(L), and the local convection coefficient, hx(L), at the trailing edge, x = L.

(b) Calculate the average temperature of the plate surface, Ts.

(c) Plot the variation of the surface temperature, Ts(x) and the convection coefficient, hx(x), with distance on the same graph. Explain the key features of these distributions.
